Swiss firm files roaming suit against AT&T

OvumSwiss firm Starhome, one of the driving forces behind cellular roaming, said yesterday that it has filed a patent infringement lawsuit against Roamware, AT&T Mobility and T-Mobile USA in the United States District Court for the District of Delaware. Starhome's complaint alleges infringement of its patents in the way they provide international roaming.
The Complaint accuses the defendants of infringing US Patents 6,920,487 and 7,231,431, each entitled “System and Methods for Global Access to Services for Mobile Telephone Subscribers.” Starhome is seeking damages and a judgment enjoining further infringement.
“Starhome's products and services provide innovative wireless mobility solutions to enhance international roaming,” said Neta Bloch, General Counsel of Starhome. “Starhome appreciates the significant value our patents confer to our business and intends to aggressively protect our rights.”
The Patents cover the core technology of the Starhome Intelligent Call Assistant and the Starhome Home Short Code system, among other services. The Starhome technology is used to convert unrecognized home short codes into valid phone numbers.
The Starhome also helps overcome international dialing difficulties by automatically correcting or completing misdialed numbers.
Eitan Achlow, CEO of Starhome explained: “Over the course of the last 10 years, Starhome has spent a considerable amount of time and resources in developing the Home Short Code and the Intelligent Call Assistant solutions, both of which are included in our patent-protected portfolio.
“Starhome invests heavily in intellectual property and realizes the importance of protecting these innovations and technology.”
Starhome says that it manages and maintains over 900 roaming solutions for over 178 mobile operators in 118 countries worldwide.
